Black and white
If you’re more interested in photographing people than the colourful surroundings, then consider converting your images to monochrome. Getting rid of the colour helps to simplify busy scenes and allows the expressions on people’s faces to come through more directly. It also gives images a documentary feel. Some of the greatest fairground photography is in black and white (check out Susan Meiselas’s portrayal of carnival strippers from the 1970s). And at night, the extreme contrast you get at any brightly-lit event creates patches of highlights and shadows that play brilliantly to the strengths of black-and-white photography.
